Relationships between Ear Number per Plant and Drought Tolerance in Maize Hybrids
摘要
Abstract
[ Objective ] Drought stress is always the restricting factor of food production in our country. Screening gerplasm with high drought resistance has been the important direction for millet breeding. [ Method ] This study was conducted under a natural drought stress condition in the field, and took the economic yield and botanic dry weight as the test characters. With the drought resistance index ( DTIg) as the identifiable index, 1 200 sets of national gerplasm of setaria italica were evaluated. [Result]The result of the evaluation was; first grade 116 sets with the highest resistance, second grade 242 sets with higher resistance, third grade 391 sets with median resistance, fourth grade 385 sets with weaker resistance and fifth grade 66 sets with the weakest resistance. But there were 15 sets that failed to be grained in the test. [ Conclusion] The setaria italica with high drought resistance will be the important and precious germplasm for millet breeding.关键词
